ENTACT completed site remedial work and in-situ solidification and stabilization (ISS) of impacted soils at an eight-acre former manufactured gas plant (MGP) site. The project was located near industrial, commercial, and residential properties, as well as community parking areas, a recreational park, and water district facilities, including water supply wells. This comprehensive remediation approach ensured the effective treatment of impacted soils while safeguarding surrounding properties and community resources. On this project, ENTACT:

• Excavated, transported, and disposed of 52,000 tons of MGP-impacted soils
• Performed ISS of 168,000 cubic yards of impacted material using cement-bentonite-slag grout
• Constructed a temporary containment structure with a vapor management system to manage and treat spoils
• Installed a soilcrete retaining wall
• Conducted utility removal, relocation, and replacement
